MACHINE FOR GRANULATING MEDICINAL AND LIKE PREPARATIONS.

Specification of Letters Patent.

Patented Dec. 1, 1914.

Application filed April 16, 1913. Serial No. 761,471.

'1 0 all whom it may concern Be it known that I, ERNEST VVORsLEY, a subject of the King of Great Britain and Ireland, residing at Southwick, in the county of Sussex, England, have invented an Improved Machine for Granulating Medicinal and like Preparations, of which the following is a specification.

This invention has reference to an improved machine for granulating medicinal and like preparations, the main features of a machine constructed in accordance with the invention being that it comprises a rotatable drum-like member adapted to remove in successive small portions the material to be granulated from a hopper or the like and to carry the said portions of material between two relatively movable surfaces, one of which is reticular-for example, formed of wire gauze or the likewhile the other is formed by the face of a block which is gradually forced closer to the wire gauze or like surface so that the material to be granulated is simultaneously rubbed against and forced through the wire gauze or the like.

My invention is embodied in the machine illustrated in the accompanying drawing, in which:

Figure a longitudinal vertical section, and Fig. 2 a transverse vertical section of the machine.

Referring to the drawings: A is a spindle carried rigidly by the frame B of the machine.

C is an eccentric fixed on the said spindle and. D a flanged strap rotatably mounted on the said eccentric. Links E are attached by means of pins to the flange of the eccentric strap D on the one hand and on the other hand to blocks F which are pivotally mounted between two disks G that are retatably mounted on the spindle A and are intended to be continuously rotated by suitable driving mechanism such as the chain wheels X and Y, the inner end of one of the links (E) being rigidly fixed to the eccentric strap D to keep the links in proper relation to the blocks and to cause the said strap to rotate with the disks. The disks G also carry partition blocks H which are rigidly securedto the said disks between the pivoted blocks F and aresuitably shaped to permit of the said-blocks F swinging on their pivots while maintaining close conmoistened and mixed in the form of doughis fed.

The disks G together with the members of apparatus connected thereto are intended to be rotated in the direction of the arrow Fig. 1). As the disks rotate, the free ends of the pivoted blocks F are moved inward and outward owing to their connection with the eccentric strap D, each block being in turn nearest the center as it leaves the hopper and flush with the periphery of the disks G in the diametrically opposite position. The pockets in, formed between the disks by the partition blocks H and the pivoted blocks I are automatically filled as they pass through the hopper and the material carried away in them is simultaneously rubbed against and forced through the wire gauze or the like by the pivoted blocks F.

It will be observed that the blocks F are actuated positively in both their inward and outward movements so that neither gravity nor centrifugal force affects their action upon the material, and, further, that the combined action of the said blocks and the wire gauze reticular concave wall of the casing J is such that continuous and perfectly regular granulation is insured.

\Vhat I claim as my invention and desire to secure by Letters Patent is A machine for granulating medicinal and like preparations, comprising in combination a stationary hopper, a drum-like member mounted rotatably on a fixed spindle so that a portion of its periphery projects into the said hopper, a plurality of pockets formed in the periphery of the said mem ber, between disks constituting its ends, by a plurality of radial partition blocks fixed flush with the periphery of the disks and arc-shaped blocks pivotally mounted on the said disks and adapted to swing inward in contact with the ends of the said partition blocks from a position flush with the pe- 5 riphery of the disks, an eccentric fixed on the aforesaid spindle, a flanged strap mounted rotatably on the said eccentric, radial links attached to the said strap and to the said pivoted blocks, a fixed reticular mem- 10 ber closely surrounding that portion ofthe periphery of the aforesaid drum-like memher which is outside the hopper,, and means for rotating the said drum-like member together with the flanged strap.

In testimony whereof I have signed my 15 name to this specification in the presence of two subscribing witnesses.
